What is the best small business to start?
What small business
it depends what sort of demographic you are going for, what is the demand in your area, do you have the means to maintain the business, what do you want to sell, do you have any skills (knitting, craft etc) you can use?
This will depend on where you live and the business in your area currently. However, you can consider starting Antique refurbishment, Auto detailing, Babysitting, Bed and breakfast, Cake decorating and Cleaning services for businesses.
